Routing algorithms and optimisation techniques are fundamental to the evolution of Very Large-Scale Integration (VLSI) design. As chip complexity increases, the need to efficiently connect millions of ...

In this work, we propose a new signal routing method for solving routing problems that occur in the design process of semiconductor package substrates. Our work uses a topological transformation of ...

Engineers use a redistribution layer (RDL) in flip-chip designs to redistribute I/O pads to bump pads without changing the I/O pad placement. However, traditional routing capacity may be insufficient ...

Charles Pfeil is an Engineering Director in the Systems Design Division at Mentor Graphics. My first experience with computerized printed-circuit-board (PCB) design was in 1978 when I acquired two ...
